Space probe Cassini dove headlong into the massive, icy plumes of liquid that spew from the surface of Saturn's moon Enceladus. It managed to get some amazing images of the southern pole of the moon (pictured here), but sadly a mysterious software glitch prevented it from transmitting data about the moon jizz back to Earth.

At least we can console ourselves with this artist's rendering of what it would look like to be zooming through Enceladus' plumes if they were visible to the naked eye.
